If the AUTOHOLD switch is pressed
without depressing the brake pedal
while AUTOHOLD is operating
(AUTOHOLD active indicator light in
instrument cluster is turned on), the
message “Depress Brake Pedal and
Operate Switch to Release” is indicated
on the multi-information display to
notify the driver to depress the brake
pedal.
If any of the follow ing conditions occurs
while the AUTOHOLD function is
operating (AUTOHOLD active indicator
light is turned on), the parking brake is
applied automatically and the
AUTOHOLD function turns off. For the
Electric Parking Brake (EPB)
operation, refer to the Electric Parking
Brake (EPB) on page 4-64.
The ignition is switched OFF.
There is a problem with the
AUTOHOLD function.
Hill Launch Assist (HLA)
▼ Hill Launch Assist (HLA)
The HLA functions to assist in
accelerating the vehicle from a stop on
slopes. When releasing the brake pedal
and depressing the accelerator pedal to
accelerate the vehicle from a stop while on
a slope, the function prevents the vehicle
from rolling. The HLA also operates when
reversing on a slope.
The braking force is maintained
automatically after releasing the brake
pedal on a steep slope.
For manual transmission vehicles, the
HLA operates when the vehicle is tilted
rearward with the shift lever in a forward
gear, and operates when the vehicle is
tilted forward with th
e shift lever in the R
position.
For automatic transmi ssion vehicles, the
HLA operates when the vehicle is tilted
rearward with the s elector lever in a
forward gear, and operates when the
vehicle is tilted forward with the selector
lever in the R position.
WA R N I N G
Do not rely completely on HLA:
HLA is an auxiliary device for accelerating
from a stop on a slope. The system only
operates for about 2 seconds and
therefore, relying only on the system, when
accelerating from a stop is dangerous
because the vehicle may move (roll)
unexpectedly and cause an accident.

The vehicle could roll depending on the
vehicle's load or if it is towing something. In
addition, for vehicles with a manual
transmission, the vehicle could still roll
depending on how the clutch pedal or the
accelerator pedal is operated.
Always confirm the safety around the
vehicle before starting to drive the vehicle.
NOTE
HLA does not operate on a gentle slope.
In addition, the gradient of the slope on
which the system will operate changes
depending on the vehicle's load.
HLA does not operate if the parking
brake is applied, the vehicle has not
stopped completely, or the clutch pedal
is released.
While HLA is operating, the brake pedal
may feel stiff and vibrate, however, this
does not indicate a malfunction.
HLA does not operate while the
TCS/DSC indicator light is illuminated.
Refer to TCS/DSC Indication/Indicator
Light (Turns on) on page 7-32.
HLA does not turn of f even if the DSC
OFF switch is pressed to turn off the
TCS/DSC.

Mazda Radar Cruise
Control (MRCC) (Manual
Transmission)
*
▼Mazda Radar Cruise Control
(MRCC)
The MRCC system is designed to maintain
headway control
*1 with a vehicle ahead
according to your vehicle's speed using a
front radar sensor to detect the distance to
the vehicle ahead and a preset vehicle
speed without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the
vehicle ahead detected by the MRCC
system.
Additionally, if your vehicle starts closing
in on the vehicle ahead such as if the
vehicle ahead brakes suddenly, a warning
sound and a warning indication in the
display are activated simultaneously to
alert you to maintain a sufficient distance
between the vehicles.
Also refer to the following before using
the MRCC.
Front radar sensor (page 4-204)
WA R N I N G
Do not rely completely on the MRCC:
The MRCC system has detection limitations
depending on the type of vehicle ahead
and its conditions, the weather conditions,
and the road conditions. Additionally, the
system may be unable to decelerate
sufficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the
brakes suddenly or another vehicle cuts
into the driving lane, which could result in
an accident.
Always drive carefully and verify the
surrounding conditions and depress the
brake pedal or accelerator pedal while
keeping a safe distance from vehicles
ahead or on-coming vehicles.
Do not use the MRCC system in the
following locations. Using the MRCC
system at the following locations may
result in an unexpected accident:
 General roads other than highways
(Driving under these conditions using the
MRCC system is not possible.)
 Roads with sharp curves and where
vehicle traffic is heavy with insufficient
space between vehicles, or roads where
frequent and repetitive acceleration and
deceleration occur (Driving under these
conditions using the MRCC is not
possible).
 When entering and exiting interchanges,
service areas, and parking areas of
highways (If you exit a highway while
headway control is in use, the vehicle
ahead will no longer be tracked and your
vehicle may accelerate to the set speed).

Do not rely completely on the MRCC with
Stop & Go function:
The MRCC with Stop & Go function system
has detection limitations depending on the
type of vehicle ahead and its conditions,
the weather conditions, and the road
conditions. Additionally, the system may be
unable to decelerate sufficiently to avoid
hitting the vehicle ahead if the vehicle
ahead applies the brakes suddenly or
another vehicle cuts into the driving lane,
which could result in an accident.
Always drive carefully and verify the
surrounding conditions and depress the
brake pedal or accelerator pedal while
keeping a safe distance from vehicles
ahead or on-coming vehicles.
Do not use the MRCC with Stop & Go
function system in the following locations.
Using the MRCC with Stop & Go function
system at the following locations may
result in an unexpected accident:
General roads other than highways
(Driving under these conditions using the
MRCC with Stop & Go function system is
not possible.)
Roads with sharp curves and where
vehicle traffic is heavy with insufficient
space between vehicles, or roads where
frequent and repetitive acceleration and
deceleration occur (Driving under these
conditions using the MRCC with Stop &
Go function is not possible).
 When entering and exiting interchanges,
service areas, and parking areas of
highways (If you exit a highway while
headway control is in use, the vehicle
ahead will no longer be tracked and your
vehicle may accelerate to the set speed).
 Slippery roads such as ice or snow-bound
roads (Tires could spin causing you to
lose vehicle control, or the stop hold
control may not operate.)
 Long, descending slopes (to maintain
distance between vehicles, the system
automatically and continuously applies
the brakes which could result in the loss
of brake power.)
 Slopes with a steep gradient (The vehicle
ahead may not be detected correctly,
your vehicle may slide while stopped by
the stop hold control, and it may
accelerate suddenly after it starts
moving.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
For safety purposes, switch the MRCC with
Stop & Go function system off when it is not
being used.
Leaving the MRCC with Stop & Go function
system turned on when it is not in use is
dangerous as it could operate
unexpectedly, resulting in an accident.

Do not get out of the vehicle while the stop
hold control is operating:
Getting out of the vehicle while the stop
hold control is operating is dangerous as
the vehicle may move unexpectedly and
result in an accident. Before getting out of
the vehicle, switch the MRCC with Stop &
Go function system off, shift the selector
lever to the P position, and apply the
parking brake.
CAUTION
If your vehicle is towed or you are towing
something, switch the MRCC with Stop &
Go function system
off to prevent an
unexpected operation.
 Turn the system off when the vehicle is
running on a chassis roller.
NOTE
The MRCC with Stop & Go function
system does not detect the following as
physical objects.
Vehicles approaching in the opposite
direction
Pedestrians
Stationary objects (stopped vehicles,
obstructions)
If a vehicle ahead is traveling at an
extremely low speed, the system may not
detect it correctly.
If there is a structure on the road or an
object (such as a monorail) at a low
height off the ground in front of the
vehicle, the system may operate.
Therefore, do not use the MRCC with
Stop & Go function.
Do not use the MRCC with Stop & Go
function system under conditions in
which close proximity warnings are
frequently activated.
During headway control travel, the
system accelerates and decelerates your
vehicle in conjunction with the speed of
the vehicle ahead. However, if it is
necessary to accelerate for a lane
change or if the vehicle ahead brakes
suddenly causing you to close in on the
vehicle rapidly, accelerate using the
accelerator pedal or decelerate using
the brake pedal depending on the
conditions.
While the MRCC with Stop & Go
function system is in use, it does not
cancel even if the selector lever is
operated and any intended engine
braking does not occur. If deceleration
is required, lower the set speed or
depress the brake pedal.
